Geologic Model
Overview
The geologic structure is defined by the block model, which defines the geometry and rock types, and the velocity model, which defines the material properties based on the rock types and depth. A more general description of the model is available on the USGS Menlo Park website.

Block Model
Details related to the geometry of the block model, including area of coverage, fault geometry, and fault block hieracrhy.
Velocity Model
Details related to how the material properties are assigned to each rock type.
